A training device, including a collapsible stand having a central support shaft and a plurality of legs. The plurality of memories may be configured to store and present the data in response to a write data path and a read data path. A room-temperature solution process may be used to provide a relatively uniform and relatively highly-adhesive organic semiconductor layer in a simple and economical manner. The interface is operatively coupled to a set of one or more stage-1 switch elements, and is adapted to aggregate the working and protection channels of the communications network on a selected one of the set of stage-1 switch elements. The invention further permits simultaneous transfer to a variety of electro-chemical batteries, which can possess different storage chemistries. The method continues with the processing module dispersed storage error encoding the updated directory metadata to produce encoded directory metadata slices and transmitting one or more data slice write requests to the DSN that each include a first transaction number.
